Following initial geological assessments, Poland was identified as having one of the largest reserves of unconventional natural gas in the European Union. The Poles, seeking to diversify their energy sources, met the news with tremendous fanfare. However, shale gas development often requires voluminous speculative activity before the gas can be successfully extracted - an activity which has been rare in Poland, where a lack of critical infrastructure coupled with bureaucratic red tape in the permission process has led to slow growth in exploration activities. This article examines the current situation in Poland's unconventional gas and oil development. [ABSTRACT FROM AUTHOR]

We estimate a regional spatial panel simultaneous-equations growth model, using a five-step new estimation strategy that generalizes an approach outlined in Kelejian and Prucha. The study region consists of the 418 Appalachian counties 1980−2000. Estimates show feedback simultaneities among the endogenous variables, conditional convergence with respect to the respective endogenous variables, and spatial autoregressive lag and spatial cross-regressive lag effects with respect to the endogenous variables. A key policy conclusion is that sector-specific programs should be integrated and harmonized and that regionally differentiated development policies may yield greater returns than treating all locations the same. Estimamos un modelo de crecimiento de panel espacial regional por ecuaciones simultaneas, utilizando una nueva estrategia de estimación de cinco pasos que generaliza una enfoque descrito en Kelejian y Prucha. La región de estudio comprende los 418 condados Apalaches 1980-2000. Las estimaciones muestran simultaneidades de retroalimentación entre las variables endógenas, convergencia condicional con respecto a las variables endógenas respectivas, y un retardo espacial autorregresivo y efectos de retardo regresivos cruzados espaciales con respecto a las variables endógenas. Una conclusión clave sobre políticas es que los programas sectoriales específicos deberían estar integrados y armonizados, y que las políticas de desarrollo diferenciadas regionalmente podrían producir mejores retornos que si se tratasen todas las localizaciones del mismo modo.

Abstract. In his response to Closure in Cole's Reformulated Leontief Model (Jackson et al. 1997) Cole presents the mechanics of his solution. His spreadsheet demonstration of the model, however, fails to fully address the conceptual issues and model specification concerns raised in our critique. His demonstration does enable us to provide a sorely needed formalization that pinpoints the inconsistencies in his model. While we join with Cole in urging modellers to strive for clarity, transparency, and utility, we caution against allowing these goals to cause us to lose sight of internal consistency requirements.
